\ BY 2am zzze'i --i -w WWW ma ADJUSTABLE BED CARRIAGE WITH ADAPTER UNITBACKGROUND OF THE INVENTION 1. Field of the Invention Since the widthdimension of bedding is essentially standardized, i.e. twin size 37%inches, double size 52 /2 inches, and queen size60 inches, the presentinvention generally relates to a bed frame having four legs or two legsthat is adjustable to preset widths for snugly engaging various standardsized bedding in a positive, non-spreading arrangement with the siderails of the frame being retained against the bedding over a substantialportion of the lengths thereof.

2. Description of the Prior Art Numerous four-legged bedframes have beenknown that are adjustable in the horizontal transverse dimension toenable the frame to be used with different sized bedding.Conventionally, the headboard is secured to the ends of the bedframe byemploying bolts or similar screw-type fasteners. Such bedframes usuallyemploy screw-type clamping devices to secure the cross rails in theiradjusted position.

Serious problems exist in this type bed carriage, some of the moreimportant of which are the following. Since the headboard is normallysupported above the floor by the bolts or other screw-type fasteners,which are attached essentially at one place along the heigth of theheadboard, the headboard rapidly becomes unsteady is use, sometimesreferred to as headboard wobble. Second, the screw-type clamping devicesfor the cross rails have resulted in certain problems arising from aloosening of the clamps or an inadequate initial tightening orpositioning thereof, such as the bedding falling through,leg collapseand undue stress on the end posts of the headboard. Third, considerabletime and labor is required to set up such prior bed frames, includingthe mounting of the frame ends to the headboard and the setting of theproper width of the cross rails to the bedding.

While some, but not all, of the foregoing problems, are resolved bytwo-legged bed frames which are also known, such frames have additionalproblems. In prior two-legged frames, the ends of the bed frame are secured to the headboard by conventional hooks on the ends of the bedframe, and the hooks engage the pins in the slots of the headboard.However, such slots are normally spaced apart as much as two to threeinches and more greater than the width of the bedding. As such, littleor no support is given to that portion of the bedding which is at thehead end of the bed on the wider headboards. Attempts to use a slat atthe head end is unsatisfactory for the many failings of slats, e.g.,warping, breakage, deforming bedding, etc. Further, the cross-rails atthe foot end of the bed frame are still subject to the samedisadvantages explained above.

Finally, bedframes having fixed width dimensions are known but up to nowhave always required screw or bolt-type connections for the headboard inview of the variable distance between the headboard slots asaforementioned. Again, such connection leads to headboard wobble,lengthy set-up time, unsightly appearance, etc.

SUMMARY OF THE INVENTION The present invention provides a bedframehaving cross members adjustable to preset widths which provide thebedframe with the correct width for receiving and supporting bedding ofdifferent standardized widths, e.g. twin size, double size and queensize.

The present invention also retains the bedframe side rails against thebedding so that the box spring is always resting on the horizontalflange of the side rails throughout a major portion of the length of theside rails and the vertical flanges of the side rails are snugly againstthe box spring.

A principal object of this invention is to provide a bed carriage in theform of a frame that includes at least one cross rail that can beadjusted into preset lengths so that the rails will be retained in anypreset position in a secure manner without the use of externallyactuated fastening means or tools for manipulating such fastening means.

A second principal object of this invention is to provide a bed carriagein the form of a frame which hooks into the slots of the headboard andcan be rapidly assembled so that the side rails fit snugly to thebedding throughout a major portion of their length even though thedistance between the slots may be as much as 2 or 3 or more inchesgreater than the width of the bedding.

A further object of the invention is to provide a bedframe which isrelatively inexpensive to manufacture, very easy and rapid to set up andyet dependable and long lasting as well as being trouble free inoperation.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout.

BRIEF DESCRIPTION OF THE EMBODIMENTS ILLUSTRATED IN THE DRAWINGSReferring now specifically to FIGS. 1-9 of the drawings; the bedcarriage of the present invention includes a frame generally designatedby reference numeral 30 which includes a pair of longitudinallyextending side rails 32 interconnected by a pair of substantiallyparallel cross rails 34 with an end board such as a headboard 36 andfootboard 38 being supported from the side rails with adapter brackets40 such as those shown in Ser. No. 791,241, filed Jan. 15, 1969, now US.Pat. No. 3,644,948, issued Feb. 29, 1972 connecting the end board of theside rails 32.

Each side rail 32 is in the form of a right angular rail between thecross rails 34 having a horizontal flange 42 and a vertical flange 44.Each end portion of each rail may terminate in a vertically disposedplate portion 46 in which the horizontal flange 42 is turned downwardlywith the transition area being designated by the numeral 48. Thetransition area may be separated from the horizontal flange 42 by anotched area 50 (as illustrated in FIG. 6). For rigidity, the verticalflange 44 can be provided with a longitudinal outwardly embossed rib 52(See FIG. 7) and the terminal end of the plates 46 are inturned as at 54and provided with a pair of upwardly extending outwardly offset tongues56 for engagement with the adapter bracket 40.

If desired, the flange or plate 54 at either or both ends of the railsmay be identical and may be provided with apertures for receiving boltsfor securing the frame rails to the end board (such as illustrated inFIG. I). This construction provides for lateral flexibility at the endportions of the rails 32 to enable attachment to end boards of differentdimensions. However, it is contemplated that the present invention willbe used primarily with headboards only without any footboard,

' such as footboard 38. Therefore, vertically disposed plate portions 46would not be necessary at the foot end of the side rails 32, and thefoot end of frame 30 would be similar to that illustrated in FIG. forframe 132.

Each of the cross rails 34 includes two substantially downwardly openingchannel-shaped members 58 and 60 with the channel-shaped member 58 beingslightly larger than the member 60 and telescopically receiving themember 60. As illustrated, one larger or outer channel-shaped member 58is secured to one side rail 32 adjacent the headboard while the otherouter channel-shaped member 58 is secured to the opposite side railadjacent the foot end of the bed. The smaller or inner channel-shapedmember 60 is provided with a plurality of longitudinally spacedsubstantially square apertures 62 therein while the largerchannel-shaped member 58 includes a plurality of downwardly offsettongues 64 which have their free end extending toward the side rail 32to which the channel-shaped member 58 is attached. The apertures 62 andthe offset tongues 64 are so arranged that in the three preset adjustedpositions of the cross rails, all of the tongues are engaged withapertures when the cross rails are adjusted to their smallest presetdimension such as twin size as illustrated in FIGS. 3 and 4. In theintermediate or double size and in the extended or queen size position,only two of the tongues 64 are engaged with apertures 62. In the fullyextended position and possibly in the intermediate or double widthposition the cross rails may be provided with an auxiliary supportingleg 66 to provide support for the center of the cross rail to prevent itfrom sagging. Also, each end of each cross rail 34 is provided with asupporting leg 68.

The supporting legs 66 and 68 are illustrated in FIGS. 5 and 9 andinclude a split tubular member or any other suitable tubular member 70having a horizontally disposed lug 72 at the upper end thereof and twovertically disposed lugs 74 projecting therefrom. The two verticallydisposed lugs 74 receive a pivot bolt 76 therethrough which also extendsthrough apertures formed in the channel-shaped member 60 while thehorizontal lug 72 underlies an aperture in the channel-shaped member 60for receiving a fastener bolt 78 which is accessible through an aperture80 formed in the overlying channel-shaped member 58. Notches 82 areprovided in the outer channel-shaped member 58 to enable access to thepivot bolt 76 to permit assembly of the leg 66 with the cross rail 34when desired. The holes for the fastening bolt 78 may be countersunk inthe top surface of the channel-shaped member 60 and should be orientedto either side of the pivot bolt so that the leg may be assembled in anadjusted position substantially centered irrespective of whether thecross rail is in the outermost position or in its intermediate positron.

The leg 68 at each end of the cross rail is substantially the same ascenter leg 66 and is designated by the numeral 84 and attached to thechannel-shaped members 58 and 60 by rivets 86 and 88 (as illustrated inFIG. 7) for providing a permanent and rigid connection between the endlegs 68 and the cross rails 34. All of the legs are provided with asuitable glide or caster 90 on the lower end thereof.

The connection between the ends of the cross rails 34 and the side rails32 is substantially the same at each end of the cross rails and includesa rivet-type connector 92 at one corner of the channel-shaped member 58or 60 with the rivet being disposed through the horizontal flange 42 ata point adjacent the vertical flange 44. The horizontal flange 42includes an arcuate slot 94 which receives a second rivet 96interconnecting the flange 42 and the underlying channel-shaped member58 or 60 with the arcuate slot also receiving the rivet 96 and servingas a guide and limiting means for the swinging movement of the crossrail in relation to the side rail 32.

The horizontal flange 42 is also provided with a pair of downwardlystruck oppositely extending tongues 98 which are received within a notch100 having converging side edges communicated with the end edge of thechannel-shaped member 58 or 60 to limit the swinging movement of thecross rail to a perpendicular relation to the side rail with thestructure of the tongues 98 serving to retain the flat surface of thecross rail against the undersurface of the horizontal or bottom flange42.

As a further stabilizing feature, the bottom flange 42 may be providedwith a single downwardly offset tongue 102 which is disposed adjacentthe free edge of the bottom flange 42 and which is received in a notch104 formed in the channel-shaped member 58 or 61) and further serving toretain the top surface of the cross rail rigidly against theundersurface of the bottom flange 42 for stability and also permittingpivoted swinging movement of the cross rail to a stored positionunderlying the side rail as illustrated in broken lines in FIG. 6. Withthis construction, the cross rail may be connected to the side rail atfour relative corner positions when in perpendicular relation thereto,that is, by the rivet 92, the rivet 96, the two tongues 98 and thetongue 102. Thus, a rigid structure is provided and one also in whichthe channels 58 and 60 may be disconnected from each other and swung toa stored position in underlying relation to the side rail to which it isattached for shipment in a compact arrangement. The cross rails can thenbe easily set up by grasping each of the channel-shaped members andswinging them into perpendicular relation to the respective side railsand then interlocking the channel-shaped members 58 and 61 by engagingthe tongues 64 with the openings 62 to the desired preset position. Theframe is then in a locked rigid position to receive the bedding.

FIGS. -13 illustrate another embodiment of the bedframes of thisinvention generally designated by the numeral 132 and which includes apair of side rails generally designated by numeral 132 and a pair ofcross rails generally designated by the numeral 136. Each side rail 132may be made by stamping sheet metal, but is in the form of an angle ironmember having a bottom or horizontal inwardly extending flange 140 andupwardly or vertically extending flange 142 at the outer edge thereof.The upwardly extending flange 142 may include a longitudinal rib 144thereon for rigidity which terminates outwardly of the cross rails 136.One outer end of each rail 134 terminates in a vertical plate portion146 that is approximately in alignment with the vertical flange 142 withthe horizontal flange 1411mming downwardly and forming a lower portionof the vertical plate 146 with the transition area designated by numeral148. The outer end of each vertical plate 146 is provided with anoutwardly angulated plate 158 ter minating in an inturned end plate 152.The plates 146 and 148 have reinforcing ribs 154 therein. The end plates152 are provided with horizontally disposed vertically spaced attachmentslots 156 therein. The other end of each rail 134 is cut off outside thecross rail 136 as at 153.

The cross rail 136 is illustrated in detail in FIGS. 11, 12 and 14 andincludes a pair of nesting and telescopic angle members 158 and 160secured to the side rails 134. The angle member 160 includes a pluralityof pairs of keyhole slots 162 in the vertical flange thereof and theangle member 158 includes a plurality of pairs of projecting tongues 164in the vertical flange thereof in which the tongues face oppositely andare shaped and arranged to interlockingly and detachably engage with thekeyhole slots 162 as illustrated in FIG. 12. Leg assemblies 166 areprovided at each end of the cross rails 136 and a central leg may besupported from the cross rails when the cross rails are in their mediumand maximum extended positions. Each leg assembly includes a rightangular bracket 168 having a depending tubular member 170 at the lowerend thereof adjustably receiving a glide 172 or other supportingstructure by virtue of the use ofa screw-threaded adjustable connection174. The bracket 168 is attached to the vertical flange of the members160 and 158 by fastener bolts and nuts or the like 176 with similarrivets being employed to secure the central leg in position (see FIG. 11

Each cross rail 136 is attached at its end to the horizontal flange 140of the side rails by use of a fastener such as a rivet 178 with a downstruck tongue 180 being provided to receive the free edge of the leg toorient the cross rail in perpendicular relation to the side rails whenin unfolded condition.

FIG. 14 illustrates still another embodiment of the bedframes of thisinvention which employs a pair of side rails 184 of metal construction,which again preferably may be formed of stamped metal. The vertical endplates 186 may be of sufficient length to provide a degree of lateralbending for the end portions of the rails. The free end of the plates186 is provided with a transversely extending flange 188 projectingoutwardly from the plate portion 186. Flange 188 terminates in a narrowflange 190 having a pair of downwardly opening hooks 192 thereon fordownward engagement with the mounting pins in a vertical slot 194 in aheadboard. A transversely extending abutment member 196 is provided atthe upper end of the flange 188 which together with the flange 188serves as the bearing surface of the hook connection to engage thesurface of the end board leg 198 and thereby stabilize the end board inrelation to the side rails.

In this construction, a cross rail 200 which is very similar to crossrail 136 in FIG. 10 is used as well as a tension member 202 whosefunction is described hereinafter. The only difference between crossrail 2110 and cross rail 136 of FIG. 10 results from the fact thatduring assembly of this bed frame, cross rail 200 is under slightcompression. Accordingly, the cross rail 2110 is provided with a meansto prevent contraction when adjusted to one of the preset positions.Such a means is illustrated in FIG. 15 and includes an upwardly strucklug 216 on angle member 210 which is so positioned thereon to engage theleading edge 214 of angle member 212. In order to accommodate the threepreset positions of cross rail 200, there are three lugs 216 properlypositioned along the length of angle member 210.

It should be noted that the lugs 216 are only slightly upwardly struckso as not to protrude above the upper surface of angle member 212, forotherwise the lugs 216 might tear or impair the bedding. Similarly, theprojecting tongues 164 and slots 162 are positioned on the side of theangle members 158 and 160 and 210 and 212 so as not to tear or otherwisedestroy the bedding supported on the bed carriage.

The bed frame 184 in this embodiment of the invention as well as thebedding carried thereon are supported at the head end by the headboard198 and at the foot end by vertically adjustable legs 199, which aresimilar in construction to legs 166 of FIG. 13. This is in contrast tothe previously described embodiments of the invention which contemplatethat the frame include four support legs and that the headboard (andfootboard as in FIG. 1) be supported in an elevated position above thefloor surface. By utilizing the headboard to support the head end of thebed, the headboard is rigidified in the bed construction and instabilityis thereby significantly reduced. The foot end of the frame 184 can beraised or lowered by means of the vertically adjustable legs 199 so asto be level with the head end of the bed. The height of the head end ofthe frame is, or course, determined by the height of the pins in theslots 194 and, therefore, may vary from headboard to headboard.

Thev two-legged bed frames of this invention include as an essentialelement a tension member, such as a wire rod or strap 202, whichinterconnects the side rails 184 at or near their lengthwise center. Thewire or strap 202 has ends, such as hooks 203, which engage incorresponding apertures 185 in the side rails and is pre-set in lengthso that when installed, the distance be tween the vertical flanges ofside rails 184 is essentially equal to the standardized width of thebedding to be supported on the frame. In order to accommodate the threeseparate standardized bedding widths, it is necessary with thisembodiment of the invention to provide three different length crossmembers 202.

By reason of the accurate preset dimension of cross member 202 the siderails 184 will be held snugly in engagement with the side edges of thevarious size standardized bedding to thereby support the bedding on thehorizontal flange of the side rails 184 over a major portion of theirlength. This arrangement not only assures that the bedding will besupported by the horizontal flanges 187 of the side rails 184 but alsowill provide a rigidifying structure inasmuch as the bedframe, headboardand box spring become an integral stressed unit which thereby preventstwisting or canting of the bedding in relation to the bedframe and thebedding will serve to retain the bedframe in substantial rectangularconfiguration with the headboard being substantially perpendicular tothe side rails.

Further, this arrangement assures that irrespective of greater spacingbetween the slots in headboard than the width of the bedding, thepre-set tension member 202 will always pull the central portion of siderails 184 into snug engagement with the bedding or box spring. Since thecross-rails 200 are also pre-set to the exact width of the bedding, thebedding or box spring will be snugly supported on the horizontal flange187 of the rails 184 from at least their central portion to the footend. In order to accommodate the slightly greater spacing between theslots 194 of the headboard, the rails bend slightly in that portionbetween the hooks 192 and where the tension member 202 is connectedthereto. The extent of the bending depends upon the spacing between theslots 194 in the headboard and, depending upon the length of the plate186, more or less bending will be concentrated in the plate 186 ascompared to the right angle portion of the side rail 184. As a result ofthis bending of the side rail 184 in conjunction with tension member202, the two-legged frame of this invention can be assembled onendboards whose distance between slots may vary as much as two to threeinches and more greater than the width of the bedding to be supportedthereon. Hence, regardless of variation in the slot separation, thisframe can be readily used on all types of headboards.

A further feature of this form of the invention is the downwardlyindented portion 189 of the horizontal flange 187 which accommodates thehook 203 of the tension member 202. The identation allows the tensionmember 202 to be recessed below the supporting surface of the horizontalflange 187. In addition, when the angle members 210 and 212 are alignedwith the side rails 184 for shipment, the angle member abuts thedownwardly struck lug 191 and is frictionally retained in that positionby engagement with the lower surface of the indented portion 189.

To assemble the bed carriage illustrated in FIG. 14 it is only necessaryfor the person to swing members 210 and 212 of cross rail 200 to theirrespective extended positions perpendicular to the side rails 184 andconnect the angle members in the desired pre-set position. One side rail184 is mounted on the headboard 198 by engaging the hooks 192 in slot194. The tension member 202 is installed between the side rails. Thenand only then is the other side rail 184 mounted on the headboard tothereby bend the rails the necessary amount to accommodate the slotspacing of the particular headboard 198. The legs 199 are thenvertically adjusted to level the bed, if necessary.

FIG. 17 illustrates another two-legged embodiment of the bedframes ofthis invention which utilizes standard or conventional angle iron rails204 as the side rails. The standard angle iron rails 204 areinterconnected by a cross rail 206 at the foot end thereof, similar tocross rail 200 of FIG. 14, and a tension member 208 interconnects thecentral portions of the side rails, similar to member 202 in FIG. 14.The ends of the side rails 204 are provided with conventional attachinghooks and/or bearing plates 207 for mounting in the slots of headboard209. In this construction, the side rails are of conventional angle ironconstruction with the cross member 208 retaining the side rails snuglyagainst the bedding. Depending, of course, on the construction of theend portion 207, the side rails 204 may assume a bowed configurationalong that portion of their length from about where the tension member208 interconnects the side rails to where the side rails are mounted inthe slots of the headboard.

Additionally, it is contemplated for this form of the invention that thecross rail 206 may be of the fully adjustable type or of the rigid typesince the primary concept is the pulling of the central portions of thesides of the frame inwardly by the tension member 208 to the exactstandardized width of the bedding irrespective of the distance betweenthe slots on the headboard. Accordingly, whether the cross rail 206 isfully adjustable, or rigid to accommodate only a single width bedding isnot material to this concept.

The general purpose of the bedframes is to provide a frame that has bothstrength and versatility and yet be relatively simple so that a customermay set up the frame himself or an inexperienced person may easily setup the frame. In addition, the frame will lock positively at presetwidths to receive the standardized widths of bedding without the use ofbolts and clamps and external parts that are subject to loss. The crossrails lock together into three preset dimensions that are standardizedfor the three standardized bedding sizes,

twin, full and queen sizes and the cross rails lock together into thecorrect width without nuts, bolts, clamps or the like. Thus, the widthof the frame opening is limited to the size of the bedding and cannotopen any further than its preset position and once the box spring is inplace, the rails cannot close in.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention.
